zen ofthe United States, residing atDexter,in

have' invented certain new and useful .Iln'

provements in Traction-Engines; and I do hereby declare the following to be a full,elear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to traetion-engines and it consists in the novel construetion and combination of the parts hereinafter fully described andclaimed.

In the drawings,` Figure l isa'side view of the engine partly in section. Fig. 2 is a plan view of the engine from above. Fig. 3 is a cross-section taken on the line m ce in Fig. l.

A is the frame of the engine, and B is a circular guide at its front end.

rC is a turn-table which is journaled in the guide Il and provided with teeth c around its edge. The turn-table is provided with a slot ZJ, and D is a main ground-wheel which is arranged in the said slot. This wheel is journaled in any approved manner,as upon a shaft d, which is carried by the said turn-table.

E is an upright carried by the frame A, and e is a vertical driving-shaft arranged over the axis of the turn-table and having a toothed pinion c secured on it. arranged a little to one side of the axis of the turn-table and is provided with a toothed wheel d', which gears into the pinion e', so that the ground-wheel is driven from the shaft e.

F is the motor, which is mounted on the frame A. Anyapproved-motor maybe used, but a motor of the kind commonly known as a gasolene-engine is preferably used, and its cooling water-tank,gasolene-reservoir,and all other necessary additional parts are carried by the frame A. The vgasolene engine or motor is connected to the shaft e by intermediate driving mechanism of any approved construction.

G is a horizontal shaft journaled in the upright E, and g are beveled toothed wheels which connects the two shafts G and e. An auxiliary fly-wheel g' is secured on the shaft and1 may also carry the customary friction c utc l, Be itknown that 1, HERMAN emits, a citi# The ground-wheel is His a pulley mounted on the shaft G, and h is a pulley on the crank-shaft of the engine. i H is a belt passing over the pulleys H and h. The engine may, however, be connected with the shaft e in any otherapproved manner.

I is a tongue seeured to the turn-table and projecting through a slot z' in the front end of the frame A. XVhen the engine is steered by a horse, the horse is hitched to the tongue I, which is arranged radially of the center of the turn-table and parallel with the ground-Wheel D. When the engine is steered by hand, a

toothed pinion j is arranged in gear with the teeth `c on the periphery of the turn-table. The pinion j is secured on a steering-shaft J,whicl1 is 'journaled in the frame A'. The shaft J may be revolved by any approved` intermediate mechanism from any part of the frame.

K is a hand steering-wheel which is securedv on a shaft k at the rear part of the frame.

VL is a driving connection, such as a belt or chain, which passes over wheels or pulleys at and m, secured on the shafts k and J, respectively.

The rear part of the frame is supported on two casters M, which permit the engine to be steered in any direction and to turn very sharp corners.

What I claim is 1. In a traction engine, the combination, with a frame provided with a circular guide, of a turn-table j ournaled in the said guide and provided with a slot, a single ground-wheel supported by the said turn-table and arranged in the said slot to one side of the axis of the turn-table, a drivingshaft journaled concentric with the turn-table and above it, and toothed drivin g-wheels constantly connecting the' said shaft and ground-wheel, substantially as set forth.

2. In a traction engine, the combination, with a frame provided with a circular guide, of a turn-table journaled in the saidguide, a single ground-wheel supported bythe said turn-table on one side of its axis, asteeringtongue arranged radially of the axis of the turntable and parallel with the said groundwheel, a driving-shaft arranged on the axis of the turn-table, and driving devices con` stantly connecting the said shaft with the ground-whee1, substantially as set forth.
